E-government efforts have facilitated the information and services available on the Web, and have been fueling the information sharing and collaborations across governmental units and organizations. The sharing and collaboration requires vertical and horizontal interoperability and integration of government operations and infrastructures providing the facilities for sharing and communicating. Creating interoperability faces many technical, organizational, managerial and strategic challenges.

Interoperability is a property referring to the ability of diverse systems and organizations to work together. Infrastructures are public and quasi-public utilities and facilities that are typically used by large numbers of different users, such as the Internet and libraries. The way infrastructures are used typically changes over time in a process of evolution and adaptation. The ability of information and service harvesting, discovery, sharing, dissemination, management, preservation, can be facilitated with the interoperable infrastructure.

This minitrack will provide e-Government researchers the opportunity to exchange theories, methodologies, experience reports, literature and case studies in infrastructure and interoperability. Interoperability research range from the technical to organizational, policy and strategic levels and we solicit for papers covering these aspects. Papers in the field of e-Government induced data-and process-based integration, enterprise architecture and transformation, which are also beneficial to practitioners or have a strong relationship with practical problems and case studies, are strongly encouraged. We promote a diversity of research methods to study the challenges of this multifaceted discipline focusing on various aspects of interoperability and also theoretical papers and papers from developing countries.

Topics and research areas include, but are not limited to:

1. -Development, implementation, maintenance of projects, system and enterprise architectures and infrastructures
   

2. -System, data- and process-based integration
   

3. -Information reuse, information quality, ontologies and semantic modeling
   

4. -Cross-organizational modeling and visualization ranging from the organizational to technical level
   

5. -Infrastructure and enterprise architecture planning, alignment, strategies and governance
   

6. -Infrastructure facilities and interorganizational development projects
   

7. -Technical, semantic, organizational, managerial aspects of interoperability
   

8. -Design and application of architectures and infrastructures for interoperability
   

9. -Organizational and/or policy perspectives on the dynamics of the infrastructure and interoperability process and barriers to interoperability
   

10. -Theoretical contributions and contributions from developing countries
    

11. -Interoperability standards, principles and frameworks
    

12. -Service-oriented architectures, web services, semantic web services, web service orchestration and composition
    

13. -Best practices and case studies at all levels of government, including local and transnational government
    

14. -Longitudinal studies that span over generations of e-Government implementations
